"The doors have sensors to detect nearby objects, which should keep them from striking objects or limbs that might be in the way. If that's not cool enough, the driver's-side door can open and close for the approaching driver without a single human touch."

And Greg Kumparak at TechCrunch wrote that " I was hoping I might walk away from my short test drive in Tesla's Model X without the desire to throw down $130,000 I don't have... Alas."

The unveiling of the oft-delayed Model X SUV comes at an interesting time for Tesla and the rest of the industry.

Volkswagen is reeling due to its emissions cheating scandal. And VW's woes have dragged down the stocks of many other major auto manufacturers around the world.

But Tesla's stock has held up relatively well during a rocky third quarter. Shares are actually up more than 10% this year.

Tesla has been a volatile stock, but you could also call it Teflon Tesla.

Investors have largely shrugged off concerns about sluggish sales in China, the possibility that low gas prices will hurt demand for electric cars and a valuation that could be considered the equivalent of its vehicles' Insane Mode.

Trip Chowdhry at Global Equities Research wrote in a report early Wednesday that "Tesla just killed every other auto manufacturer."

Chowdhry raved that Tesla has re-defined the SUV. He's predicting that Tesla could sell 89,000 vehicles overall in 2016 and report revenue of $9.11 billion. Those estimates are higher than Wall Street's consensus forecasts.

And Chowdhry's price target on Tesla's stock is $385 -- more than 50% higher than current levels.

Amazingly enough, that price target is conservative compared to some of his fellow analysts.

Stifel's James Albertine thinks Tesla could hit $400.

Albertine wrote in a report Wednesday that concerns about further delays to Model X production because of design issues now appear to be "overblown" and that he's also not too worried about the possibility that Model X sales will eat into Tesla's Model S sedan demand.

And then there's Tesla uber-bull Adam Jonas of Morgan Stanley. Jonas has a price target of $465 for Tesla.

Jonas wrote in a report earlier this week that the VW emissions scandal could benefit Tesla. People interested in environmentally friendly cars may be more apt to buy electric vehicles instead of ones that run on diesel.

Still, investors should be cautious. Tesla's shares, like its cars, are expensive. They trade for 100 times 2016 earnings estimates. Tesla can't afford to stumble with a valuation that high.

Tesla is a very risky stock. It's unclear how strong demand will be for the batteries it's making for homes and small businesses.

The company is also spending a lot of money on its gigafactory in Nevada, a plant that will allow it to produce even more batteries. The gigafactory is key to Tesla's plan to eventually sell a more affordable electric car, dubbed the Model III.

Any problems at the gigafactory could hurt Tesla's chances of moving from a niche luxury car maker to a mass market auto company that could truly rival the likes of Ford(F), GM(GM) and Toyota(TM).

And Tesla could soon face more competition as well. Rumors are running rampant that Apple(AAPL) may start selling cars within the next few years.

Tesla remains a cult favorite of car junkies and Wall Street traders. But the stock is not for the faint of heart.
